We developed a technique for searching for useful information suitable for the user's work from a database consisting of the past projects and delivering it to the user with the aim of improving operational efficiency. Previously, information sharing systems have been developed, but there was the problem that information was not used if the user oneself did not retrieve it. Useful information suitable for the user's work can be delivered automatically by using our original technique, which are keywords extraction and relevancy evaluation by TF · IDF · ITF between search results and the user's work. The developed system was applied to information equipment design and was confirmed that it was able to deliver useful information with 80% accuracy.
